Trump and Modi announced the two countries were finalizing a $3 billion arms deal.
"I believe the United States should be India's premier defense partner," said Trump, "and that's the way it's working out."
Trump spoke during an event at Sardar Patel Stadium in Gujarat state's Ahmedabad city to a crowd of Modi loyalists estimated at around 100,000, telling the attendees that the military partnership between the U.S. and India was strong and that his administration "looks forward to providing India with some of the best and most feared military equipment on the planet."
"We make the greatest weapons ever made," said Trump. "Airplanes. Missiles. Rockets. Ships. We make the best and we're dealing now with India. But this includes advanced air-defense systems and armed and unarmed aerial vehicles."
